Flow around a car at low Reynolds number

Flow around a car at low Reynolds number, starting from rest. This simulation is a first pre-study of the flow behaviour for a recent BMBF project together with Daimler--Benz/Stuttgart.

• Distribution of temperature/concentration via Boussinesq model
  
  

  Visualization via temperature distribution, starting from the (interior) heated shape of the car (first, 0.9 MB), and via tracing of concentration, starting from the inlet (second, 1.1 MB).
  

  
  
  

• Pressure
  
  

  Visualization via pressure plots, shaded (first, 1.1 MB) and via isolines (second, 4.1 MB).
  

  
  
  

• Streamfunction
  
  

  Visualization via streamline plots, shaded (first, 1.1 MB) and via isolines (second, zoomed, 2.1 MB).
  

  
  
  

• Velocity
  
  

  Visualization via vector plots (vectors, 3.2 MB) in a zoomed area.
